CALGARY, Alberta (AP) — Johnny Gaudreau and Matthew Tkachuk each had a goal and two assists as the Calgary Flames beat the Ottawa Senators 6-1 Sunday night to preserve their slim playoff hopes.
Mikael Backlund, Michael Stone, Dillon Dube and Mark Giordano also scored for Calgary. Jacob Markstrom stopped 19 shots for his 19th win.
The Flames moved eight points behind Montreal for the fourth and final playoff spot in the North Division. To make the postseason, Calgary needs to win its remaining four games against the division-worst Canucks and the Canadiens needs to lose its remaining two games against Edmonton in regulation.
Josh Norris scored the lone goal for Ottawa, which lost in regulation time for just the second time in its last 11 games. Anton Forsberg gave up four goals on 23 shots. He was replaced by Filip Gustavsson, who made 11 saves in relief.
Knowing they were facing elimination, the Flames played desperate hockey from the opening faceoff.
After Gaudreau hit the post in the opening minutes, the Flames forward was not denied on his next opportunity. On a fast break, Gaudreau took a stretch pass from Giordano right on the tape and slid a delicate backhanded shot between Forsberg’s pads while falling to the ice at 10:39 for his fourth goal in his last six games.
Meanwhile, the Senators, who were coming off a 4-2 win over the Winnipeg Jets on Saturday, could not get anything going in the first. They went more than 15 minutes without firing a puck on Markstrom and were outshot 10-3.
Calgary opened the floodgates in the second period, scoring three times by the halfway mark.
Backlund put the home team up 2-0 just 17 seconds in to cap off a good cycle play in the offensive zone.
The Flames added to their lead at 4:38 when a patient Gaudreau found Tkachuk in the slot for his first goal since April 2.
At 10:05, Calgary made it 4-0 on its 23rd shot when Stone’s slap shot from the point blasted past Forsberg, chasing the Senators' goalie from the game.
Gustavsson started the contest on the bench following his 27-save performance on Saturday.
That goaltender change may have briefly sparked the visitors as Norris scored a minute later on a beautiful backhand pass from Drake Batherson.
But the Flames added two more in the third period to put the game out of reach. Dube sealed it on the rush with a one-timer at 6:45 before Giordano made it 6-1 at 13:53.
Calgary finished 3-5-1 against the Senators this season.
